What to fix

  1. Warning

    2 of 8 announced prefixes have no ROA (RPKI not found): 87.58.0.0/20, 2a13:5942:1020::/44.

    Without a ROA, networks cannot tell your routes from a hijack.

    Fix: Create a ROA for each at your RIR portal, with origin AS211318 and a max length equal to the prefix length:

    87.58.0.0/20 AS211318 max-length /20
2a13:5942:1020::/44 AS211318 max-length /44

    Fix: Try again in a minute.
